About 100 Fort Carson soldiers deployed to West Africa in November to help build treatment facilities to house Ebola patients and caretakers are back home with their families now that their quarantine period has wrapped up.

It appears a lack of communication allowed the sick Ebola patient to be released back into the community. The CDC now believes at least 12-18 people, including children, may have been exposed. Now the Agency must track down all possible contacts and monitor them, and isolate them if they become ill. CBS4 Medical Editor Dr. Dave Hnida explains the medical detective work that must now take place, as well as the legal authority health officials have to contain the spread of the virus.
